, Myinvention relates to that kind ofkitchen utensils `which are used in the culinary arts to slice potatoes into chips of varlous-slzes and of manifold patterns; and the objects of my invention are toiprovidey a1 potato chipper which, first, is ofh such substantialy construction Vas to withstand thefrequent and rough use of a large cuisine or scullery, second, affords the cook means to do the slicing 19 of potatoesmostexpeditiously and conveniently, third, 'is of such simple kconstruction astobe' easily cleaned, and fourth, without eXtra parts by a simpleprocess can be adapted to the cutting of the various sizes and fancy y and useful patterns known to the art, as there are pommes s ouflles, pommes juliennes, pommes-gaufrettes?, Saratoga chips and manymore; v

IV attain these objectsby the device illus-k trated in the laccompanying drawings' in which, e Figurell is a perspective view of the kassembled device. l 'A Y f.

Figure 2 is a bottom view of same.-A Figure 3'is a side view -of the knife., 4 Ffigure 4: isV an end'view of the adjusting sha I 'Similar' numerals Vrefer to similar parts throughout thev several views. g i l The device is assembled on a boardg, the

end 6 of which is yshaped to offery convenientk grip forthe hand. There is an aperture 7 which servesto hang up'the -devicefwhen not in use. y i, Y V On the board is mounted by two screws 8 the rectangular plate 9. Thatplate is springy and: its free'end rests on the adjustingshaft 10 for the whole length ofwhioh the board 5 is cleared out.' The two round ends of shaft the shaft do not have to' be'fully journaled but they rest in suitable slots, extending from the top downward in thefbearing plates k'11.

The shaft is held in positionendwise hva l9'is facing vthat* 10 are supported by bearing plates lliwhichy arel screwed onto both sides of the board.` Since the tensiony of plate 9 presses down. at all times upon'the shaft',`v the round ends" of shows numerals 1, 2, 3 `and 4', right-angularly vdisplacedfrom eachother. Y i

'lhe shaft 10.is rectangular in the center, its fourrsidwes ,14, 15, 16and 17 registering,

respectively,l with the numerals 1, 2, 3 Vand 1 on the face ofthe knob. In the rotation enumerated the foury sides of the rectangular part ofthe shaft have successively increasing distances from the center Vof shaft 10 so that side 14 is abouttangential toV the round ypart of the shaft, side 15 yis alittle Vfurther away from it, the distances being still greater for sides ,16l and 17 Knife 18 is tiltedupwardat the end 19 at which it faces plate 9. "Its other end 2O is tilted downward. It rests on the ends of four .screws 2l whichnare inserted in the board 5 from the bottom and protrudeover its top. The knife is held down by the two sides 22, which yare rotatably retained onV the board 5 by bolts 2 3. The bolts 24 in the sides 22 fity into slots 25 and 26 in the knife and in the board,l respectively. Clearances are cut into the board fromy the bottom, correspending to those'slots and accommodating wing nuts 27 on the ends of bolts 2 4.

When the wing nuts are loosened up, the

. Sides 22 canbe swung away from thedevice around bolts 23, and the knife may be taken out 'and turned around, sothat .its end 20, extending upwards fromithe board', faces plate 9 inthe samev way in, which'the end plate in the drawing.

* The tilted end 19'of theknife has Aa sharp corrugated edge produced by suitable flutes pressed, milled or ground'into the material.

yThe other :end 20oftheff'knife `runs to 'a straight sharpkni-fe edge. Below fthe knife f fis aclearance cut v28 inthe board. There isa-lso a clearance out 29 inthe sides, accommodating the tilted kend of'knifef18 and fromy f y there on tothe back the bottoms of the sides are slightly cleared aWLYfto, allow clearance for `theknife and` spa-ce below saidknife, requiredfor adjustments `of the knife.v At the rea-rend, `rbelow the tilted end offtheknife,

theiboard is chamfered downwardt give Y clearancefor that tilted endv ofthey knife.

" The devicefunctions as follows:

` The operator grips the `6 slides 'd the potato along plate 9 against the edge of the knife and as he continues the stroke, part of the potato is cut away at the bottom, falling out below the knife through opening 28. The slices of the potato come out of the bottom, fluted corresponding to the cor rugated edge of the knife.

By turning the potato through a variety of acute angles rangingup to a right angle, on each successive cutting stroke, or by holding it in the same direction all the time is one means by which the appearance of the slices can be given a great variety. But the greatest advantage is imparted to the device by the novel adjusting shaft, allowing the cutting of the slices at any thickness desired. When assembled for the first time the screws 2l on the bottom of the board are adjusted in such a way that, with the knife resting on those four screws, the Vbottom of the corrugated edge of the knife is slightly above the level of the top of plate 9, when the side of the square shaft corresponding to the index figure 3 on the knob is turned up. If I turn the knob to position 4, the free end of plate 9 is raised so that its top faces the corrugated edge of the knife; the plate drops below the corrugated edge when the knob is turned to position 2 and the vertical distance between the corrugated edge and the plate is still further increased when the knob is set to position l.

In the position l the machine cuts heavy slices, for potatoes puffed a la madeleine. For thinner, but similar slices the knob is setto position 2, the machine making potatoes fluted a la Vichy. Turning the potato for successive cuts and having the knob set to position, slices pierced in a gated pattern are obtained, pommes gaufrettes, pommes frittes, sometimes termed julienne potatoes I obtain by setting 4 of the knob. V

If I now turn the. knife around so that the corrugated edge 19 is in the back of the machine, whereas the straight edge 20 faces plate 9, taking the previous position of the corrugated edge, I can, by corresponding adjustments of the knob obtain plain puffed potatoes, German fried potatoes or Sa-ratoga chips.

I The rectangular section of the adjusting shaft may bereplaced by a. triangular, pentagonal or any polygonal section, thus oli'ering less or more positions of adjustment for other varieties of potatoes. The other parts ofl the machine, means for adjusting the heights, the sides, etc., may be adjusted ina variety of ways a description of which would lead too farfin this specification but which, of course, all fall under the scope of my in# vention.y Instead of having a rectangular shaft with eccentric round ends, the shaft may be round and eccentricy in respect to the journaled ends, means being provided at the same time to clamp or set said shaft at any angle desired.

I claim:

l. A potato chipper of the kind described, com arising a frame, a plate and a detachable kni e both mounted on the top of said frame, with one edge of said knife adjacent, opposed, and in spaced apart relation to one end of said plate, said knife having cutting edges on its opposite ends and being reversible lengthwise to present either edge in adjacent, opposed relation to said plate end, side rails mounted on the top of said frame, near the opposite edges thereof, pivoted thereto to swing transversely thereover and over said knife in a plane parallel to the plane of the top of said frame, and means to clamp the swingable ends of said side rails upon said knife, to detaohably and reversibly retain said knife in operative relation to said frame and said plate end.

2. A potato chipper ofthe kind described, comprising a frame, a spring plate fixedly connected at one end to the top of said frame, with its opposite end free and vertically adjustable relatively to said frame to a de,- tachable knife normally mounted in Xed position on top of said frame and lengthwise reversible relatively thereto, having cutting edges on its opposite ends with one edge adjacent, opposed, and in spaced relation to the adjustable free end of said plate, clam ing means to retain either edge of said kni ein spaced, operative, position relatively to the free end of said plate, and a rotatable, polygonal sided, eccentric shaft mounted transversely in said frame, in supporting, rotatably movable engagement with the bottom face of the free end of said spring plate, adapted, by different degrees of rotation, to cause the various sides of said shaft to engage said plate and adjust the free end of said spring plate to variable, predetermined positions of vertical adjustment, relatively to the top of said frame and to the adjacent edge of'said knife.

3. a potato chipper, in combination with a frame, a plate mounted on said frame, one end of said plate being vertically adjustable in relation to said frame, a knife provided with oppositely disposed, differently patterned, alternative potato cutting edges, and clamping means adapted to fix said knife in said frame in alternative cutting position, so that one or the other knife edge faces said plate, each allowing the cutting of a differently surfaced potato chip, and sothat thev thickness of said chips depends on the vertical adjustment of the end of said plate.

4. In a potato, chipper, the combination ywith a frame, a plate mounted in said frame,

one end of said plate being vertically ad justable in a multiplicity of positions of predetermined height in relation to said frame, a knife provided with oppositely disposed,
